1.安装配置kerberos
1.1 安装服务端：kdc
yum install -y krb5-server krb5-libs krb5-workstation
1.2 配置服务端：
配置/etc/krb5.conf
includedir /etc/krb5.conf.d/
[logging]
default = FILE:/var/log/krb5libs.log
kdc = FILE:/var/log/krb5kdc.log
admin_server = FILE:/var/log/kadmind.log
[libdefaults]
default_realm=HNA.CN
dns_lookup_realm = false
ticket_lifetime = 24h
renew_lifetime = 7d
forwardable = true
rdns = false
# default_realm = EXAMPLE.COM
default_ccache_name = KEYRING:persistent:%{uid}
[realms]
HNA.CN = {
kdc = bd-50.hna.cn
admin_server = bd-50.hna.cn
}
[domain_realm]
.bd-50.hna.cn = HNA.CN
bd-50.hna.cn = HNA.CN
配置/var/kerberos/krb5kdc/kdc.conf
[kdcdefaults]
kdc_ports = 88
kdc_tcp_ports = 88
[realms]
HNA.CN = {
#master_key_type = aes256-cts
#kadmind_port = 749
max_life = 12h 0m 0s
max_renewable_life= 7d 0h 0m 0s
acl_file = /var/kerberos/krb5kdc/kadm5.acl
dict_file = /usr/share/dict/words
admin_keytab = /var/kerberos/krb5kdc/kadm5.keytab
supported_enctypes = aes256-cts:normal aes128-cts:normal des3-hmac-sha1:normal arcfour-hmac:normal camellia256-cts:normal camellia128-cts:normal des-hmac-sha1:normal des-cbc-md5:normal des-cbc-crc:normal
}
配置/var/kerberos/krb5kdc/kadm5.acl
*/admin@HNA.CN *
2 安装客户端：
yum install -y krb5-workstation krb5-libs
配置客户端：
scp /etc/krb5.conf name@host:/etc/krb5.conf
3. Kerberos使用：
创建数据库：kdb5_util create -rHNA.CN -s
创建远程管理员：
kadmin.local
Addprinc root/admin@HNA.CN
4.kerberos服务配置：
chkconfig krb5kdc on
Chkconfig admin on
Service krb5kdc start
Service kadmin start
测试：
kinit root/admin@HNA.CN
